Im trying to tq my rocker arms, i have the comp cam magnum 1.75 roller rocker kit. ive tried to tq like the service Manuel says,(cylinder #1 tdc, tq exhaust 1/2/7/8 to 22) but the rocker arm always stars pushing the valve down far before i get to 22. what am i doing wrong?

I got the instructions from comp, they say finger tighten them tell the pushrod has tension then turn it 1/2 turn more. do all this with the valve off the lobe of the cam. does this sound right?

Yup. They know their stuff. That's how we did mine.

Do you have adjustable rockers? If so, they don't get torqued.

so wait how the hell do i tighten these things up?

on the LS you get the valve off the lobe and tighten the rocker bolts to 22ftlb or something like that. they are non adjustable, thats why people have to measure to find what pushrod length they need on the LS motors or they just guess because there isn't any adjustment to the rockers.

ok well everytime i do that the valve starts getting pushed down far before the tq wrench says im at 22

Well just went ahead and did what comp says, finger tighten then half a turn. Trucks starts faster, and revs good ill test drive it tomorrow dont wanna **** the neighbors off.

LSx rockers are pretty fool-proof, torque to 22ft lbs bump it over a few times/run it and double check, no other adjustment in them other than making sure the pushrods are the right length if you changed up anything else in the valvetrain...
